Toall whom it may 'con-cern:

Be it known-that I, GEORG KIRKEGAARD, .a l

citizen of the United States, and a resident of t-he city of New York, in the county of New York and State of New York, United States of America, have invented certain 'new and useful Improvements in Bottle Filling and Capping Heads, of whiohthe following i is a specification.

My invention rela-tes .to new and useful improvements in bottle filling and capping enlarged sectional side elevation of my im-` Flg. 3 1s a sectional planv view showing a paclnngde-- proved bottle capping head.

vice which I use in carrying out my invention, the section being taken through the line 3 3 of Fig. 2. Fig. 4'is a similar sectional plan view of .the same parts as are shown in Fig'. 3, .this view showing the parts in difl'erent relativeposition. Fig. 5 is a sectional side elevation of a forming-head or collar which I use for locking the caps to bottles. Fig. 6 is a sectional plan view4 of certain parts of my apparatus, the section being taken through the line 6 6 of Fig. 2. Fig. 7 is aperspective view of the bottle cap which I have invented and which may be used to advantage with the apparatus herein shown and described.

vLike -characters .of .reference designate corresponding parts in all of the figures.

10 designates a supporting base. 1.1., 11 are vertical standards which are attached to this base and arranged to sup-y port certain of the parts.

12' designates a.- supportin -carriage ,splined upon these standards an arranged to be held thereon .by means of hand screws 13, 1 3. Ata point 14 on this supportingcarriage is pivoted a hand lever 1 5. 16 designates a slot in this hand lever.

part ofthis vspindleis connected with a lever 15 byizmeanfsjof thepin, 17'. l A' collar 21 is attached to the spindle 20 by means of screws ,'22, and.- a .compression spring 23 placed between this collar and the portion 19 of `thesupporting carriage is'a'rranged to hold .the spindle and its-connected parts normally -in Atheir raised position in which position they are shown in Figs. l and 2.

The spindle 20 is arranged to carry a oompression shaft 24 which 1s pressed outward from the spindle by a compression spring 26. This compression. shaft 24 is constructed to form a shoulder 27 and a plunger 2 8 which extends below it-and .which is somewhat sma'llen in .diameter than the shoulder 27. The lower end of the compression shaft may be provided withareoess and -a permanent ma net 29 may be `placed within this recess if eisired. y

30 designates a 'forming-headwhich is constructed of three sectors 31, 32' and 33 which are substantially alike in construotionand which are held together by means of springs 34 and 35. The inner surfaceof each of these sectors is provided with a cam groove 36. The construct-ion and operation of this forming-head is specifically described ina former application for patent Serial'.

Number 336,831, tiled by me October 1st, 1906.

40 designates a piston which is attached to Ithe lower end of spindle 20 as is shown at 41. This piston is'arranged to carry two achingrings42, 42. The lower portion of tiih piston isprovided'with an annular rim 43 which extends inward under the forming-head 3 0 and thereby holds the latter between this rim and the lower end of the spindle. This rim also prevents the compression spring 26 from forcing the compression shaft and forming.- head out of the spindle 20. The vertical distance between the 'rim 43 and the bottom ofthe spindle 20 is preferablyV somewhat y .greater than the vertical height of the form- --.ing-head 30 so that the latter is held somewhatloosely in place between these parts. '50 designates a portion of the frame or carriage. 12 which is .arranged to form a. l

.cylindrical filling chamber 5'1. The upper portion of this part ofthe frame or carriage the u ward movement thereof. 20 designates a spindle which is verticallyli guidedin thecarriage l2 at 18. --The upper 52 esignate's aninlet port'to which a supyply pipe may bl-:connected 53l isavalve i .which .controls this inlet port' 'andconnects )it with theheylindricallligchamber; 51, r

54 is an outletpassage from the cylindrical fillingrchamber which is connected with the discharge pipe 55 through a safety valvel 56 which may be of any well known construction.

60 designates a packing device which comprisesl an annular ring 61 of rubber or other suitable resilient material which is arranged to be held within clamping pieces 62, 62. These clamping pieces a-re held between a supporting-sleeve 63 and a ring 64. The supporting sleeve is provided with depending ribs 65 and these ribs serve the purpose of holding the ring 64 at a suitable distance from the main portion of the sleeve 63. lhese parts may be held together and attached to the portion 50 of the supportinghead vor carriage by means of screws 66.

(57 designates a locking wrench which is provided with ahandle 68 and which is rotatably supported and guided by the sleeve G3 and ring 64. ."lhis locking wrench is provided. with cai-n surfaces 69, G9 which are arranged to engage with similar cam sur-` faces upon the clamping pieces ('52. The infaces (59 eno'a in(y with the similar cam surfaces upon the locking pieces 62 will cause the latter toA be moved inward and this will in turn compress the packing ring until it tightly surrounds the neck of the bottle 70.

vfio

The bottle 70 may be supported by a suitable standard 71 which is adjustably connected to the base 10 by means'of a rod 72 and a clamping-screw 73.

In operating this device it is necessary to set the bottle standard or support 71 in a Suitable position to support a bottle 70 so that-fitS-n'eck will come within the packing device 60 which I have just described. After a bottle has been placed upon this standard or support the locking wrench may be turned to'cause the packing ring to be squeezed against the neck of the bottle after which the valve 53 may be opened to admit suit- -able liquid under pressure to the filling chamber 51 and thus to the bottle.

80 designates a bottle Acap which I have invented-fand which lmay-be used to advantage with this apparatus. This bottl'e cap comprises a flat disk 81 having an annularv depending flange 82 and depending yfingers or lugs 83, 83. A Cap 80 may be placed upon the lower end of the compression shaft and willV be held in place by the magnet 29. Now, when the lever 15 is depressed to move the spindle cork or other suitable material and this"will be firmly compressed against the top of the bottle through the action of spring 26. A

further movement of the Aspindle 2O will push the forming-head 30 down by the mouth of the bottle and the cam grooves 36 in this forming-head, which are arranged to operate with the projecting lugs or lingers 83, 83 on vthe cap, will cause these lugs to be pressed inward against the neck of the bottle and under the annular riinor bead 74at the-top of the bottle neck. This will securely lock the cap to the bottle. After the bottle has been filled the valve may be turned to close the passage from the source of supply to the filling chamber, in which case the movement of the .parts which Iv have just described for applying the cap to the bottle i will cause the pressure to increase. l

The filling of the bottle has of course beenaccomplished before the descent o f the spindle 20 and the piston B0 which eects the capping of the bottle as above described. At' the instant prior to the'descent of the capf` ping head there is a considerable body of -the liquid in the chamber 51 and itis desirk able to save this liquid so far as possible. I t is the purpose of the .valve 456 to open at this time and permit .the discharge of the liquid in thechamber 15 into the pipe 55.r When the piston 30 has wholly descended to complete the capping operation, substantially all of the liquid in the chamber 51 has been expelled into said discharge pipe 55.' If the operator is" sufficiently skilful the capplng head may be made to descend just before the filling of the bottle is completed, in this way expelling the liquid in the4 chamber 51 intor the bottle to complete the filling thereof instead of expelling it into the discharge pipe However, it isnot objectionable to wait until the bottle has been entirely filled before the capping operation is caused to take place. It will be observed that after the bot tlc is filled and-the capping completed, that the bottleI can be removed without. raising the carriage 12, since it can be slipped out by moving the. capping head upward slightly and then pulling the bottle laterally at its base. The bottle is then dropped out of the cavity in the filling chamber and removed.

' The forming-head 30 is constructed, 1n the manner I have pointed out, of three parts resiliently held together by means of springs 34 and 35 for the purpose of preventing `undue pressure on this head from breaking the bottle neck.

When the'cap has been secured to the boti tle thelever 15 may be released and the spring 23 will then cause the spindle and. its

connected parte to be moved upward. 'lhe packing device may then be released by returning' Athe clamping wrench baci; to its initial position after which the bottle may means; for supplying liuid. to

.be released and. the Opin-ation repeated indefinitely.
